Error messages should help identifying the topic/map

The log message [DOTX019W] currently looks like this:

[move-meta] [DOTX019W][WARN]: The type attribute on a topicref was set to ‘xxxxx’, but the topicref references a ‘yyyyy’ topic. This may cause your links to sort incorrectly in the output. Note that the type attribute cascades in maps, so the value ‘xxxxx’ may come from an ancestor topicref.

Unfortunately the message does not help to identify the <topicref>.

• I read the CONTRIBUTING file.

Expected Behavior

The message should help the user to determine the affected <topicref>.

Actual Behavior

Affected <topicref> is not reported.

Possible Solution

The message should print the linking attributes @href and/or @keyref.

Environment

• DITA-OT version: 2.5
• Operating system and version: all
• How did you run DITA-OT? Ant
• Transformation type (HTML5, PDF, custom, etc.): all

In addition to adding the source of the issue, the message itself should be shortened.

This may cause your links to sort incorrectly in the output. Note that the type attribute cascades in maps, so the value ‘xxxxx’ may come from an ancestor topicref.

Should be moved to documentation.
